HESI 799 RN Exit Exam Quizlet

Correct Answer: B

Rationale: The correct answer is B: Serum creatinine. Aminoglycosides, such as gentamicin, are known to cause nephrotoxicity, which can lead to kidney damage. Monitoring serum creatinine levels is crucial in assessing renal function and detecting any potential kidney problems early. Choices A, C, and D are incorrect because urinalysis primarily assesses urine composition, serum osmolarity measures the concentration of solutes in the blood, and liver enzymes are not directly impacted by aminoglycoside antibiotics like gentamicin.

Correct Answer: C

Rationale: Placing the client on NPO status is the priority action for a client with acute pancreatitis. This step is crucial to rest the pancreas, prevent pancreatic stimulation, and decrease enzyme production. By withholding oral intake, the digestive system is given a chance to rest and recover. Administering intravenous fluids may be necessary but should come after placing the client on NPO status. Pain medication can be administered once the client is stabilized. Assessing the client's abdomen for distention is important but is not the initial priority in managing acute pancreatitis.

Correct Answer: D

Rationale: The correct answer is D. A post-lumbar puncture headache, ranging from mild to severe, may occur as a result of leakage of cerebrospinal fluid at the puncture site. This complication is usually managed by bed rest, analgesics, and hydration. Choices A, B, and C do not directly indicate complications associated with a lumbar puncture. Pain in the lower back when moving legs, a sore throat when swallowing, and nausea with a feeling of vomiting are not typical complications of lumbar puncture.

Correct Answer: C

Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.

Correct Answer: A

Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.
